    electronics test equipment

    refurbished? not 100% sure but i think you can get some decent ex lab equipment from pawn shops and e-waste facilities.. you could even try your luck with craigslist or ebay. despite what people think ebay can actually be a great resource for used equipment.

    My old high school gym

    Is the system indoor or outdoor? i dont really see why cables would be in that bad condition.. ive seen systems just like this installed for upwards of 30 years and its still running strong.. yeah definitely the area you live in effects the degradation of the cable but i dont see any reason why...

    Does a Minor Crack in a solar panel effect its Efficiency?

    since this setup is used in a live ammunition range for military training i think someone used the panel for cover and a bullet casing must haven fallen onto the panel.. its impossible for it to have been a direct bullet hit cause it would've made a bigger crack haha. also could have been from a...

    Does a Minor Crack in a solar panel effect its Efficiency?

    Hey guys I have an older 300w panel that gets used for charging up batteries through a regulator during the day for a 24/7 UHF/VHF repeater setup.. recently i Have noticed the panel has a small crack through the glass in one of the corners. does this affect efficiency at all? Regards, Lightshow

    Charging 2 12v batteries separately

    the only way the batteries are connected is through the solar charge controller which doesnt connect the batteries to each other anyway. I was wondering if there was a charger which supported this? charging two batteries at the same time when they are completely isolated?

    Charging 2 12v batteries separately

    hey all, I've recently followed through on that new repeater design for the radio network at cadets (old forum post) however the plans have changed slightly from the original post since I have now realised that the repeater has two dc inputs one for backup (I assume for a 12v battery backup)...

    VHF Repeater system

    The "surperiors" keep alot of the extra info to themselves And since the radios are pre programmed they think that frequency's is not something that we need to know they basically give us the bare minimum and then tell us to deal with it.. bad i know but i cannot really argue
